But as the Galahad swings around the ringed planet Saturn, they encounter a mysterious metal pod orbiting the moon of Titan. As the teens prepare to bring the pod and its contents aboard, the crew is swept by an illness that is beyond their medical experience. Dozens of crew members fall into a comatose state, only to awaken with strangely glowing eyes. To make matters worse, the systems of the Galahad begin to fail. With time running out, can Triana and her shipmates escape the Web of Titan?
